SPECIFICATION forming` part of Letters Patent No. 714,787, dated December 2, 1902.

Applimttion led May Z5, 1897. Renewed November l, 1899. Serial No. 736,544. (No model.)

To @ZZ whom it may concern.- Be it known that I, GARRY J. DQRMANDY, a citizen of `the'United States, residing at the village of Lansingburg, county of Rensselaer, and State of New York, have invented certain new and `useful Improvements in Machines for Infoldin g theEdges of Cuff-Blanks or Like Articles, of which the following is aspeciication. y ro Myinvention relates to machines for infolding the edges of blanks for cus or like articles. lates to that class of folding-machines in which an expandingand contracting templet or die `l5 is operated to rest upon the blanks to be infolded and folders or infolders actuated to move inwardly and outwardly for folding edge portions of the blanks over edge portions of the templet, p zo- As heretofore constructed the infolders of cuff and collar infolding machines have been arranged and operated in such manner that `the several infolders would move inwardly -at the same time and outwardly at the same y time, so that when applied to infold the rounded corners of blanks the iufolders gathered in thematerial radially and when applied to infold angular corners they caused the material to bunch up in a diagonal line of direction.`

It is one of the objects of the present invention todo away with the above defect.

Another object is to provide a machine upon which a lock-corner blank maybe produced,

lock-cornerblanks heretofore nothaving been produced without two or more insertions of the blank in a machine ortwo or more machines excepting when folded by hand. This object is accomplished in the present instance 4o of myinvention by providinga templetadapted to bear directly upon the blanks upon the bed and infolders having in the machine illustrated means for operating them successively in sets, so that the infolds last formed may overlap other infolds at corners of the blanks.

A series or set of infolders are shown adapted to beoperated while others are at rest, to be succeeded by having the infolders first oper ated become stationary while others become 5o operative with the blank remaining station- More particularly my invention re-` ffor operating infolders, the mechanism of such construction that it may be reversed in movement so that the infolders may be operated in a different order, whereby in the second of two succeeding operations of the machine a blank may be formedhaving lockcorners the reverse of the corresponding cor- 6o ners of the preceding blank, and when the two blanks are laid one over the other the infolds may be entered one within the other at the lock-corners to interlock or anchor, in which position the blanks are sewed together.

My invention relates also to a construction and arrangement of segments tted to move to and fro in unison, serving through suitable means to operate the infolders in such a manner that by reversing the initiatory Inove- 7o ment of the segments as to direction the order in which the side and end infolds are produced will be reversed, with an accompanying reversal of the overlaps at the corners, with these segments so constructed and connected as to be adapted to actuate infolders for various forms of blanks in the same machine. y

My invention also relates to the segments which actuate the infolders and to their con- 8o struction and arrangement in such manner t that, after having been used to infold the side and end edges of the blanks in alternating sequence, by turning over the segments for operating either the side or end infolders the segments so turned and the infolders operated by them will move at thesame time as the other segments and connected infolders, i and thus act upon the side and end edges of the blanks at the same time when desired. oo

invention, with the same designation of parts by letter reference used in all of them.

vOf the illustrations, Figure 1 is a top view of a cuff and collar infolding machine containing my invention, in which two end and two side infolders are radially arranged upon the machine-bed and at right angles to each other, with the infolders moved outwardly for the insertion of a blank upon the bed and with the templet resting on the blank with its plates expanded, webs on the bottom of the' machine being indicated by a dotted line; Fig. 2 is another top view of the machine shown at Fig. 1, with the side infolders illustrated as moved inwardly to form the side infolds upon the blank with the templet omitted and with the end infolders shown as not having been operated upon. ,.Fig. 3 is another top view of the machine shown in the before-described figures, with the end infolders illustrated as moved inwardly to produce the end infolds in the blank, so that they will overlap at the corners the previously-made side infolds with the templet omitted. Fig. 4 is a plan View of the under side of the machine. Fig,5illustratesinanothertopviewthe machine shown at Figs. 1,2, 3, and 4, with the infolders in a position to havea blank placed on the bed by being moved outwardly and the end infolders at each of their lower ends provided with a pivoted nosing or tab bar, whereby a nosing or tab formed in .the blank thereat may be gathered in thereat over the coinciding tab or nosing end part ofa templet. (Not shown.) Fig. 6 is a top view of the machine that is shown at Figs. 1, 2, 3, and 4, with only three infolders employed and with the latter so placed upon the bed that one of the infolders is adapted by its position to form the infold upon one side of the blank, and the other two infolders are each adapted by their position and form on their inner edges to form the infolds upon one end and. part of the other side of the blank at the same time and each havinga nosing or tab recess formed therein at the corners where connecting with the side part which they infold, said infolders being adapted to operate in connection with a templet having corresponding form upon the outer edges of its plates when ex panded, which templet is shown with the arm by which it is operated to descend onto and rise from off the bed omitted. Fig. 7 is another top View of the machine shown in the other form one end and half of other side infold of e ,p the blank and so that the infold last produced will overlap at the corners the infold first made. Fig. 8 is a front elevation of the ma chine. Fig. 9 is a section taken from front to rear of Fig. 1 on the line fc3 ma, with the templet-arm, its counterpoise, and the templet-yoke, as well as the treadle and pressing mechanism, shown in side elevation. Fig. 10 is a plan view of an infolded cuff having rectangular corners and shown as broken in two parts with one of the blanks illustrated as turned over and down to show the position of the overlapping-corner infolds. Fig. 11 shows in a plan View a pair of blanks folded by the machine with the infolders shown as arranged at Fig. 7, with `the two blanks illustrated as broken apart, and one of them turned over and down to show the position of the overlapping infolds at the corners by which they are adapted to interlock and be anchored when sewed. Fig. 12 is a section taken on the line o: .fr of Fig. 5. Fig. 13 is a section taken on the line m2 :r2 of Fig. 1. Fig. 14 is a top view of a templet adapted to be used in connection with the infolders shown at Figs. 1, 2, and 3 and illustrated with its plates as expanded to form a continuous edge at the sides and ends. Figfl is a top View of the templetshown at Fig. 14 with the plates `illustrated as drawn'inwardly. Fig. 16 is a plan view of the under side of the templet shown at Figs. 14 and 15 and with its plates illustrated as expanded. Fig. 17 is another bottom view of the templet shown at Fig. 16 with its bottom plates drawn inwardly.

The several parts of the apparatus thus illustrated are designated byletter reference,

and the function of the parts is described as follows:

The letter B designates the bed of a machine embodying my invention, and which may be constructed with a heating-chamber B2, as shown in cross-section at Fig. 9, in which chamber gas may be burned or steam used to heat the bed.

The letter A designates a bearing or slideway, preferably annular in form, provided in the bed, and the letter R a slide or ring which is adapted to engage said slideway to slide therein. The ring R may be provided with an annular recess R2, as shown in crosssection at Fig. 13. Y

The letter H designates an upwardly-projected handle connected to the upper surface of the ring and by which the ring can be moved to and fro in the slideway.

The letters S designate segments, preferably arc form, each of which is adapted by IOO IIO

`its form to beentered Within the annular re- `cess R2 and which may be adjustably con- `nected therein by means of bolts b2, passing through slotted openings O to enter a threaded bolt-passage O2, `formed for convenience in the bottom oi' the recess R2. Each ot' these segments is constructed with a slot S2, which constitute a cam intermediate the segment and an infolder. The cam may have a slot partiE, which is eccentric or inclined to the direction of movement of the segment and with the said eccentric slot part connecting with a slot part C, which is concentric and hence inoperative. y

The letters I designate infolders. The infolders `shown at Figs. 1, 2, 3, and 5 have the same general form upon their infolding edges, with the exception ofthe modification shown at Fig. 5, in which a nosing ortab end is made an infoldingfeature. Each of these infolders I `is connected with a slide-bar 112,

`which meansV the infolders and their slidebars may be placed with reference to each other in any desired1 radial position upon the bed, and thus adapt the machine to use various forms and location of infolders and so `avoid the necessity of having a Vmachine for each form of cuff or collar to be infolded.

The purpose of the described slideway construction, it will be seen, is to constitute guides or devices for litting the infolder-bars tto the support to move inwardly and outwardly, which guides or fitting devices are non-integral with or separable from said support, with means for securing the same upon the support, so that they may be adapted to be changed in position orin direction, or both,

upon the support, and thereby render a single machine with one set of infolfler-bars and fitting devices therefor capable of being employed in the infolding of various forms of blanks.

Each slide-bar i2 may be fitted to be movable vertically sufficiently to permit the presss ing of the infolds between the infolders and `described hereinafter. i. pin `platesp6 at each side of the machine may bed by means to be described herein. Each of these slide-bars i2 may be provided with a slide-pin plate having upon its under side a downwardly-projected slide-pin P, adapted to move in one of the segment-slots, as will beV Each of these slidebe constructed to adjustably connect with the slide-bar proper, with which it operates by means of a bolt b4, passing down thrpugh a slot i5, formed in the slide-pin plate, and a slot` i6, formed in the slide-bar proper, with said boltsecured therein by means `of a nut on its lower end arranged to straddle and engage with the under side edges of the slot 116, and by which arrangement the slide-bar may be adjusted to regulate the position of the connected infolder relatively to the templet.

The letters W2 designate webs which may be formed on the under side of the machinebed to keep the annularly-segregated parts of the bed connected.

The letters T designate a templet which may be provided with contracting and eX- panding plates and adapted by the form of its expanded plates on their outer edges to be used in connection with the infolders illustrated at Figs. 1, 2, and 3, although the manner in which the plates of the templet T are shown to be constructed and operated to form a continuous infolding edge when moved outwardly may be applied to produce a continuous infolding edge in the same manner upon templet-plates adapted to` infold diering `forms of blanks.

Although I have shown a certain species of templet as applied to be used in connection with the infolders shown at Figs. 1, 2, and 3, 'any suitable species of templet having when IOO jonrnaled connection it connectswith an arm a, having at its ou ter end a counterpoise Y. As thus constructed, by means of the templet-handle h3 the templet can be actuated to swing down so as to have its plates rest ou a blank BT, placed upon the machine-bed, and

to beautomatically raised therefrom when IIO the blank has been infolded and the grasp on class of cuii and collarintolding machines to lwhich my invention is shown as applied.`

The templet T (shown at Figs. 1, 14,15, 16, and 17) is provided withfa stock V, having Aslideways fu and @2 opening out from each of its opposite sides, those upon one side being for convenience at right angles to those upon the opposite side, and said s lideways `are arranged in diagonally opposite corners of :the stock.

The letters d" d and d2 d? designateslidebars, those designated at CZ being arranged to move in the slideways v' and those designated at d2 to move in the slideways t2.

The letters d3 designate a slide-bar arranged to move in each of the slideways t3.

The letters p designate two plates, of which there is one secured to the under side of, so as to move with, each of the slide-bars CZ, and the letters p2 designate two plates, of which there is one connected to the under side of, and so as to move with, each of the slide-bars d2.

The letters Gr Gr designate slide-plates, of which there is one at each end of the stock, and each of these last-namedslide-plates is attached to the top of oneof the slide-bars d3, arranged in each of the slideways t3.

The letters W designate a wheel which is centrally pivoted to theV stock V at w, and the letter h3 designates a handle which is projected from the front edge of the wheel, and the letter e2 designates an ear which 'is offset from the rim of this wheel, so as to be diametrically opposite the handle h3. This wheelW is provided with a slot w5, located in part in the handle and part in the wheel, and the letter w6 designates another slot formed in the odset ear c3, so as to be diametrically in line with the slot 105, formed part in the wheel and part in the handle, between the latter and the pivoted center of the wheel.

The letters L L designate two links, each of which is at one ot' its ends pivotally connected at Z2 to one of the slide-plates G', and at its other end one of these links is pivotally connected to a slide-pin Z3, moving in the wheel-slot '105, and the other link to a slide-pin Z4 in the slot w, said slide-pins making a sliding or cam engagement with the sides of the slots in which they are placed. As thus constructed, when the handle h3 is horizontally reciprocated it reciprocatingly rotates the wheel W, and by means of the connection made between said wheel and the plates G G the latter are moved outwardly and inwardly.

The templet or blank-holder plates p2 are formed for convenience with rectangular corners at the sides and ends, and the other templet or blank-holder plates p are alike `cut away interiorly, with each of the cut-away areas a8 of the plates 1o having the same rectangular boundaries p5 and having the angularly-pointed parts pl'on the edges of their cut-away areas, with the latter so formed that when the plates are moved outwardly from the stock they will meet to form a continuous infolding edge, and when the plates are drawn inwardly the plates p2 will enter the cut-away areas of the plates p, as shown at Fig. 17, with the plates when expanded appearing as shown at Fig. 16.

The letters fm designate a slot, of which there is one formed in one of the sides of each of the plates G', and the letters fm2 designate other slots, of which there is one formed in the other side of each of the slide-plates Gr', and with said slots so located with reference to the stock that there will be one of the slots min they side of one of the slide-plates G and one of the slots m2 in the same side of the other slide-plate G at each side of the stock. Each of these slots m at its inner end has a slot part k', which is parallel to the slide-bar d3 and made to connect with a slot part k2, which is obtusely angular to the slot part lo', and each of the slots fm2 has a slot part k3, which is also parallel to the slide-bar d3 and connects with a slot part 7a4, which is obtusely angular to the slot part k3.

The letters m5 designate slide-pins, of which there is one arranged in each of the slots 'm2, constructed to make a sliding or cam engagement with the sides of the slot, and each of these slide-pins is mounted on and upwardly projected from one of the slide-bars d', which latter is connected to the upper surface of one of the plates p at diagonally opposite corners of the stock.

The letters m6 designate a slide pin, of which there is one arranged in each of the slots m to make a sliding or cam engagement therewith, and each of which pins is projected upwardly from one of the slide-bars d2, connecting with one of the plates p2, located at each diagonally opposite corner of the stock.

With the templet or blank-holder T thus constructed and its parts thus connected when the plates of the templet are drawn inwardly, as shown at Figs. 15 and 17, and the handle h3 is moved in the direction indicated by the arrow the slide-pins m6, as operated by the slide-plates G, will first move in that portion of the slot or cam m which is parallel to the slide-bar d3 and then in the obtuselyangular parts of the same slot, while the slidepins m5 will first move in the angular slot parts and then in that portion of the slot m2 which is parallel to the slide-bar d3. The plates p', connected with the slide-pins m5, will be moved more rapidly than those operated bythe slidepins lm6, and as moved outwardly will be in a position to meet and form a continuous edge with the edge of the plates p2, moved ontwardly subsequently by the action of their slide-pins While engaging with the angular parts of the slots m. When the handle h3 is reversed in its movement as to direction, the plates p2 will be drawn inwardly, succeeded by an inward movement of the plates p', whereby the former will enter the cut-away areas of the latter when being drawn inwardly,

with the position of the plates thus operated upon indicated at Figs. 14 and 16.

I will now describe a means for pressing the blanks which may be used.

The letters J designate pressers which are employed to force downwardly the infolders, and thus press in the infolds as made, and these pressers are made with heads j2, which overhang the infolders they are intended to operate upon. This head in this instance of its use is provided with a studjs, arranged to pass down freely through an opening in the machine-bed, and each of these studs at its IOO ITO

and 9.

The letterj7 designates a spiral spring, of which there is one arranged at each end of dsaid horizontal bar between the latter and the machine-tablej.

The letter L3 designates a lever having its fulcrum arranged in the lower end of the depending bar t4 with this lever, between its fulcrum and operating end, resting upon the bar js and at its operating end connecting with a foot-treadle T3, by means ofa connectingrods. As thus constructed and arranged to `operate when the foot-treadle is forced downwardly at the front the lever L3 draws downwardly the frameF and its connected presserstuds and pressers, so that the overhang of the latter will engage with and pull down the infolders, and when the pressure upon `the foot-treadle is released therefrom the spiral springs l7'7 at each end of the barjiwill actupon the latterand cause the presser-frame to rise and the pressers to ascend from off d ss shown at Fig. 12.

of these .slide-pins is arranged to engage a The overhanging heads of the pressers may be'elongated or shortened in their lateral extension,and the studs with which the heads connect may be turned in any direction to adj ust the pressers to diier'- ing locations of the infolders upon the bed.

At Fig. 5 there is illustrated a modification `ofthe end infolders shown at Figs. l, 2, and

3, and in which modification the end infolders l2 l2 are shown as slightly curved inwardly and at their lower ends constructed tolcnrve outwardly. The letter n2 designates a nosepiece, of which there is one arranged to pivotally connect at n3 with each of the end infolders I2 I2 at their lower ends. Each of these nose-pieces is curved to correspond with the incurve n4, formed in each of the end infolders at their lower ends, and each `of these nose-pieces is provided with a slide-pin a5 at that end which is opposite to the pivot- Each slot n, formed in the adjacent infolder l, as

With each of the nosepieces n2 pivotally connected at one of its ends to one of the iii-folders l2 and at its other end makinga slide-pin engagement with a slot formed in one of the infolders I when these infolders are together moved outwardly each of the nose-pieces will swing outwardly,

and when the infolders are together moved inwardly the nose-pieces will each move inwardly, and in so doing gather in the edges of a blank and carry them over a nose-piece formed on a templet of corresponding form and which is not shown.

" At Fig. 6 there areshown infolders is I3, `having on their infolding edges E2 a form 'at Figs. 6 and 7 I make no claim.

At Fig. 7 there are illustrated infolders l5 I5, each adapted on its inner edges to fiorm infolds upon one end, and part of one side of a cuff having two rounded corners and two rectangular corners and two other infolders I6 1G, adapted to infold the remaining side of the blank, with all of the infolders adapted to be attached to and detached from the bed as well as arrangedto be alternatingly operated by means of segments constructed according to my invention described herein.

To the form of the infolder edges shown The infolders shown at Figs. and 7 are illustrated merely to demonstrate the manner of applying my invention to operate successively in sets these few of the many differing forms of infolders possible and in such a manner that the infolds last produced will at the corners overlap those rst made, and also demonstrate the means whereby the infolders and segments as constructed according to my invention may be arranged upon the bed of the machine in diiering radial positions.

The handle H, by which the ring R is reciprocated in the annular slideway A, is at its lower end journaled between ears h5 h5, upwardly projected from the ring R. This handle at its lower end where pivoted has an oiset h4 and upon the under side of the latter a downwardly-projected locking-pin h6. The letter hl designates a hole or sink made in the bed into which this pin enters to register and lock the ring R in a proper position for its initial moveine'nt. This handle isshown as locked at Figs. 1, 5, and 7, and as unlocked at Fig. 2. At Fig. 6 the handle oiset h4 is shown as extended inwardly instead of outwardly from the handle, as in the other figures, with the sink placed inside of the ring, and as thus constructed is shown with the ring locked and the pin and sink indicated by a dotted line. As thus arranged to connect, as shown at Fig. 6, and also in the other figures, when the ring R is locked the slidepins of the segments which operate the infolders will be positioned at a.point between the eccentric and concentric parts of the segment-slots, so that when the ring is operated by the handle a part of the segment slidepins will move in the concentric parts of the segment-slots with the infolders which they actuate remaining at rest, while other of the segment-pins will be operated to move in the eccentric parts of the slots to move inwardly the infolders which they actuate, and when IOO IIO

the handle is operated to reverse the ring movement by its return in reciprocation the infolders at iirst actuated will have their slide-pins moved in the concentric parts of the segment-slots to be at rest while the others will in sequence be operated to move inwardly by the engagement of their segmentpins with the eccentric parts of the slots with the infolds last produced overlapping at their corners those first made. When the segments are thus provided with slots having eccentric and concentric parts, by turning over such of the segments as have been arranged to have concentric parts of the slots first engage with the segment-pins, the latter will engage with the eccentric parts of all of the segment-slots, and this will cause all the infolders to move inwardly simultaneously, and'thus infold all the edges of the blank at the same time-a desirable condition for the infolding of some kinds of blanks-and thus one machine may be adapted to bot-h kinds of infolding.

The operation of the combined parts is as follows: A blank B4 having been placed upon the bed, the templet is operated to descend onto the blank with the templet-plates preferably expanded. This being done, the ring is moved to actuate such of the sliding pins as will enter the eccentric parts of the segment-s1ots and the infolders which they actuate to move inwardly and carry the subtending edges of that part of the blank which they infold over the corresponding edges of the templet. The previously-expanded edges of the templet are then drawn inwardly from out the infolds, and the pressers are operated to descend onto and to press in such of the infolds as have been thus formed in the blank. The templet-plates are now again eX- panded, and the ring Ris moved to bring the slide-pins of the remaining infolders into thc eccentric parts of the other segment-slots to actuate the infolders they operate to move inwardly, and thus carry the remaining nnfolded edges of the blank over the expanded edges of the templet when the plates of the latter are again drawn inwardly, and the pressers are operated to descend onto the blank asbefore to press in the infolds lastl made. After the foregoing steps have been proceeded with the templet is raised from off the bed, the infolded blank is removed, and

' another placed upon the bed. To have the overlaps of the infolds at the corners produced irst upon one infold and then upon the other, so that each pair of blanks will interlock when sewed, the initiatory movement of each reciprocation of the ring R may be reversed as to direction and so that the infold first producedby one reciprocation of the ring R will be that last produced when the initial movement of the ring as to direction is reversed in a succeeding reciprocation or oscillation. If desired, however, a series of blanks may be infolded, using the same initiatory movement of the ring, and then a corresponding number infolded by reversing the initiatory direction of the rings movements. By the initiatorymovement1 refer to the first movement made by the ring from where it is locked to the bed, and thismay be in either direction. The purpose of the locking device is to facilitate the adjusting of the ring to its central position and to retain it there.

I do not wish to limit myself to a machine in which the actuating ring or slide has but two ranges of movement to permit the operating of infolders successively in sets or series, as it may be desirable to produce the infolds in more than one or two sets in some forms of blanks.

The several cam-segments or cams form a series of infolders operating instrumentalities, and-the ring to which they are connected is, broadly speaking, a means or device constructed and fitted to permit their combined arrangement in a substantially circular or ring-like form or surrounding the central portion of the machine.

What I claim as my invention is l. In an infolding-machine for cuff-blanks or analogous articles, the combination of a support for the blanks to be infolded, a templet adapted to be positioned upon and removed from the blanks upon said support, the

said templet provided with expanding and contracting plates having edge portions adapted to bear directly upon the blanks upon said support, and within edge portions ICO of the blanks, means for infolding edge pory tions of the blanks over edge portions of the templet, whereby of two adjacent blank edge portions which meet at a corner of said templet one may be turned in before the other so that the latter may overlap the former, and means for pressing the infolded blank edges upon the said support. y

2. In an infolding-machine for cuff-blanks or analogous articles, the combination of a support for the blanks to be infolded, an expanding and contracting templet having edge portions adapted to bear directly upon the blanks upon said support and within'edge portions of the blanks, means for infolding edge portions of the blanks over edge yportions of the said templet in successive operations, so thatinfolds last formed may overlap other infolds, and means for pressing the infolds of the blanks after each successive infolding operation.

3. In an infolding-machine for cuff-blanks or analogous articles the combination of a support for the blanks to be infolded, infolders constructed and fitted to move inwardly and outwardly to infold edge portions of the blanks, a part for operating infolders, mechanism actuated by said part for eecting the inward and outward movements of infolders successively in sets so that lock-corners may be formed on said blanks, said part being re.
